While I am not in the SE Missouri area, I will let you know that we used WW and were very happy with them. In fact many of our neighbors had their windows installed before we did so we waited to see how they liked them before we made our decision. The windows are fantastic. The noise on the outside of the home is minimal and the temperature regulation is great. We had great installers who checked on us several times to make sure we were satisfied. I can't say enough good things about them. Of course for every good response there is a negative response, so I would check on WW in your area see what type of responses you are getting there regarding the installers.
